Lechtal Alps East

New snow and wind slabs represent the main danger. The activity of gliding avalanches will increase.

New snow and wind slabs represent the main danger. The activity of gliding avalanches will increase.

The large quantity of fresh snow and the extensive wind slabs are in some cases prone to triggering above the tree line. Avalanches can be released, even by a single winter sport participant. These can in isolated cases penetrate near-ground layers of the snowpack and reach large size. This applies in particular above approximately 2200 m. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Such avalanche prone locations are difficult to recognise. As a consequence of warming and solar radiation, the activity of gliding avalanches will increase. An increasing number of small and medium-sized gliding avalanches are to be expected on steep grassy slopes, especially in the regions with a lot of snow, and in particular below approximately 2400 m. Areas with glide cracks are to be avoided. On extremely steep sunny slopes small and medium-sized dry loose snow avalanches are to be expected as a consequence of solar radiation.

The various wind slabs have bonded insufficiently with each other and the old snowpack. Isolated avalanche prone weak layers exist in the bottom section of the old snowpack above approximately 2200 m. The weather will be mild. The weather conditions will foster a stabilisation of the snow drift accumulations. The solar radiation will give rise as the day progresses to moistening of the snowpack on steep sunny slopes.

The avalanche danger will decrease gradually. The snowpack remains prone to triggering in some places.
